<span> In a </span>regular polygon <span>all </span>sides have the same<span> length, therefore:
x</span>² + 8x - 52 = x² - 2x + 8
x² - x² + 8x + 2x = 8 + 52
10x = 60
x = 60/10
x = 6
12 times the quantity 15 minus a number (d)....
12(15 - d) <== ur expression
Answer:
<h2>It doesn't change the volume.</h2>
Step-by-step explanation:
If we change the position of the vertex of a cone, it won't change its volume, because we're not changing its height.
When we change the position of the vertex of the cone, we are moving it to left or right, which would give a slant cone. However, its dimensions are the same. The important fact here is that the dimensions of the cone don't change, that's why it would give the same volume.
Answer:
d. $681.15
Step-by-step explanation:
Bedroom 1:
Width = 10 ft
Length = 8.5 ft
Area of bedroom 1 = length × width
= 10 ft × 8.5 ft
= 85 ft²
Bedroom 2:
Width = 11.75 ft
Length = 13.25 ft
Area of bedroom 2 = length × width
= 11.75 ft × 13.25 ft
= 155.6875 ft²
Total carpet in the two bedrooms = 85 ft² + 155.6875 ft²
= 240.6875 ft²
If the
carpet he wants to buy is $2.83 per square foot, then how much will it cost for both rooms?
Total cost for both rooms = Total carpet in the two bedrooms × cost per square foot
= 240.6875 ft² × $2.83
= $681.145625
Approximately $681.15
Answer:
If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.
